PE12316
Triple
Incremental Encoder
February 6, 2003 Preliminary (Version 1.1)
Availability:
The PE12316 is available as a replacement IC or
Netlist IP Core, fully compatible with the TI
CF32006 functionality. The replacement IC is
packaged within the popular PLCC68.

PE12316
The IP Core can be targeted to any desired
FPGA/CPLD or ASIC Technology and is
delivered within the according netlist format. The
database has been proven in a co-emulation
together with the reference part by stimulating
both devices with the same inputs and observing
the identical results on the outputs.
For FPGAs a technology with at least 20.000
FPGA Gates like XCS20 from Xilinx needs to be
chosen.
NOTE: If /A3 is left unconnected, PE12316 is
identical to CF32006.

Enhancements over CF32006:
The PE12316 has 3 counters with 24 Bit
internally. Therefore an additional addressline
/A3 is introduced on pin 6 to select the Bits 16-
23 of each channel in conjunction with the other
addressbits A0-A2.
Differences:
The PE12316 has some slight changes:
UA1X and UA2X are synchronized with the
clock, eliminating the need to place a discrete
ACT74 type Flipflop in front of these signals.
Due to this feature a latency of one clock cycle is
introduced, resulting worst case in a +/-1 counter
difference.
